Abstract

A reliable method for stacking and feeding of paper sheets being processed as duplex copies in a printing machine, such as an electrophotographic copier/dupli-cator, is illustrated. Individual sheet separators maintain positive control of each sheet when it is accepted, held in a stack of predetermined capacity, and deposited onto a transport which carries it to the next step of the printing process.

A reliable method for stacking and feeding of paper sheets being processed as
duplex copies in a printing machine, such as an electrophotographic copier/dupli- cator, is illustrated. Individual sheet separators maintain positive control of each sheet when it is accepted, held in a stack of predetermined capacity, and deposited onto a transport which carries it to the next step of the printing process.

Wireforms 1 are mounted on a flat, flexible belt 2, which is transported in the direction shown by arrows 3 around grooved pulleys 4. As the belt is indexed one wireform at a time, an opening in the wireform gaps takes place, and a paper sheet is accepted into the stack at arrow 5. After a sheet is fed in, the next indexing step closes the wireform gap securing the sheet between rubber clamp tubes 6. Sheets shown at intermediate positions 7 remain in the stack. These sheets are maintained in alignment during their dwell in the stack by side guides 8. At the bottom of the stack the process of admission to the stack is reversed, delivering the sheet to a transport which conveys it to the next processing station. For stack sizes less than the capacity of the document translator, which require a fast index, the stepping mechanism may be overrided with a synchronous motor.
